Questions, ideas for 30-Aug-2011 - “Ask the XAF and XPO Teams” webinar

XAF Team Blog
23 August 2011

We would like to make our "Ask Team" webinars more interactive and interesting. In order to do this, we want to try to collect questions and ideas from our users and address them during the webinar, rather than just waiting for questions "at runtime" or demo-ing something we planned ourselves. The next "Ask DevExpress - XAF and XPO" webinar is on 30-Aug-2011 (click here for free registration), and we would like to make the first experiment for it.

What do you think about this idea in general?

If you support it, let's make suggestions for the upcoming webinar, either in comments to this blog, the thread in the XAF forum or even in corresponding groups in social networks. For instance, the next question asked in the forums seems to be a good example:
"Why use Domain Components in AsAlias mode instead of pure persistent objects?", and it can be addressed in the webinar.

Thank you for your feedback in advance!

Need Faster Support Replies?

Once you create a new XAF ticket in the DevExpress Support Center and select XAF under the Platform/Product field, please review the following help links displayed above the Submit button. These links describe how you can collect callstacks, logs and other important diagnostic information for any .NET error. Once you collect/compile this information, forward it to us along with your support ticket. This information will ensure faster and more accurate replies from support.

In general, any idea of pre-interaction is good, i like it.

The question is what you can get from such meetings and what you can give to your customers on such "ask" webinars.

You get enough amount of issues/questions/suggestions to have general impression of potential problems

But you can rather use such meeting to give your customers a clear vision of where are XAF/XPO going to

So I would suggest you asking what kind of future (~3-6 months) do your customers want to see for XAF and what kind of options you can suggest :)

You know, waiting for silverlight-ization of web interfaces in XAF has brought so much fun to almost all of us, that sharing such clues would be really appreciated

My main question would be: what type of future you want me (as a developer) to orient to: jquery-ization of web projects (with all features supported by or silverlight-ization?

I like the idea of being able to suggest topics of discussion up front as I have watched a number of webinars of this type but have come away somewhat none the wiser in the past.

My suggestion and my biggest challenge to date, working with XAF has been a lack of understanding (on my part) of how the framework fundementals work together. In other words, when I try to do something using a view controller or something where I am tweeking the code, I stuggle to know what to change and where to update the code.

Granted I have not sat down and looked at the source code, and honestly I try to find a solution to the problem on the support website and see if anyone else has tried to do the same thing, but in general it would help if we were given a overview of how the framework fits all of these pieces together to make up the "framework".

I realise that this could be quite a task, but I certainly could do with a better understanding of the underlying mechanics of the framework.

I agree with c Pitt, it would be a great help if we had some general idea's of the lifecycles and the connection between the parts (order of events, what happens when, dependencies, generating of views, loading of data, context's of data, ...). Of course most points are here and there documented, but very fragmented without "the great picture", without coherence. Only "create a controller ...", but without description what happens under the hood. I realized already 2 small apps with XAF and still feel like a total newby.

Lately, one of my apps has shown the red cross when a user scrolled through a listview. Of course during my vacation.

Apparently something has gone wrong during the preparation of the presentation of some piece of info.

My question is: how can i quickly discover the offending row and property without trial-and-error with the debugger?

And what about some sort of automatic quarantining (and reporting) of the offending property, while keeping the view intact as much as possible?

Probably won't make it to attend the live show, but will view the recorded session. Keep up the good work and hooray for this preparatory initiative!

Thank you for all the feedback, guys! We highly appreciate it and will take it into account regarding future webinars and blogs.

@Willem: In my opinion, log files are often a very good alternative to catching exceptions in Visual Studio:

As for automatic quarantining, though it sounds very good, I doubt that it will be easy to implement it in a reasonable time frame.

There are cases when a small part can break everything or be unnoticeable for the system. Possibly, a heuristic analysis or a set of predefined rules will be required for each concrete situation.
